Back to the US-EU comparison: Thierry observes that European health systems are typically fixated on a quick ROI for any technology investment, whereas in the US, "it's not there is no concern with ROI, but [healthcare leaders] are taking the bet to modernize healthcare." The different healthcare entities in the US are free to seek a variety of ways to do things better.
The ROI from telemonitoring is hard to calculate because it comes from so many sources: early warning of serious health problems, avoided readmissions, reduction in chronic health issues, word-of-mouth publicity from patients, and a sense that this hospital serves its community. Yet this relatively low-cost investment could be considered technological innovation of the highest order.
Healthcare organizations are desperately in need of innovative ways to work their way out of the bind of rising costs and decreasing revenues, while staying true to their mission of patient care. Technology investments alone won't solve all ills, but they can enable the solution. Innovation, not ROI, is the necessary benchmark.
